The short version

  • Each has a real cost: Alibre Design perpetual licences do not include updates; maintenance is a separate yearly plan starting at $50 per year for CAD support and updates; MoI (Moment of Inspiration) it is developed by one person, so releases are years apart and there is no support organisation to escalate to when something blocks your work.
  • They diverge on capability: Alibre Design covers Parametric modeling, MoI (Moment of Inspiration) covers Direct NURBS modelling.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Alibre Design

  • Perpetual licences do not include updates; maintenance is a separate yearly plan starting at $50 per year for CAD support and updates
  • Sheet metal, PDM data management and rendering are Design Expert only at $1,999
  • Scripting is excluded from the $199 Atom3D edition
  • CAM capability is sold as separate EZ-Mill, EZ-Turn and EZ-EDM products costing up to $2,999
  • A dedicated account manager is excluded from Atom3D

MoI (Moment of Inspiration)

  • It is developed by one person, so releases are years apart and there is no support organisation to escalate to when something blocks your work.
  • There is no parametric history and no assembly structure, so a late design change means remodelling rather than editing a feature.
  • It produces no dimensioned drawings or manufacturing documentation, so anything heading for production needs a second package for the paperwork.
  • Exchange is limited to surface formats such as STEP and IGES with no native interoperability with mainstream MCAD systems, so it sits at the edge of an engineering pipeline rather than inside it.
  • Each major version is a fresh purchase, and the long gaps between versions mean a fix or a feature you need can be several years away with no interim release.
